The infiltrators claimed to have released Planned Parenthood's website databases, along with the names and email addresses of the organization's employees. They've promised to begin releasing internal emails soon.

The group claiming responsibility called itself "3301." One of its members, identified only as "E," told the Daily Dot about the political motivation behind the attack.

"Trying to mold an atrocious monstrosity into socially acceptable behaviors is repulsive," E explained. "Obviously what [Planned Parenthood] does is a very ominous practice. It'll be interesting to see what surfaces when [Planned Parenthood] is stripped naked and exposed to the public."

Planned Parenthood's chief information officer, Tom Subak, told the publication that the group had not detected any intrusion into its web systems.

"We think we have really good security, especially on flagging suspicious behavior," he said. "We have not [received any flags]."
